4 Function and System Design System Design NMS5 is an intelligent tank gauge for measuring liquid levels with high precision, and employing the latest microprocessor technology. In addition to gauging level, NMS5 can measure the interfaces between up to three liquids, specific gravity of each and discern tank bottom. To enable accurate volume calculation or simple indication, NMS5 will accept input from either an average temperature probe NMT 53x series (via twisted pair cables, HART protocol) or spot temperature element (via 3 wire Pt. 100 RTD signal). Once installed, all calibration and operating functions can be done via the user friendly Matrix program and touch sensitive keypad. Tank side monitoring and operation can be performed by the Promonitor NRF 560. Power (AC / DC) Output NMT539 NMS5 HART Temp.

Petroleum Industry From oil production to storage at an oil depot, there exists an extensive need to measure and manage a wide variety of products. Remote tank gauging and an inventory management system combined into NMS5 and a receiving computer is an ideal way to measure and manage tank contents. Chemical Industry A wide choice of products are available in the wetted parts construction manufacturing industry, to ensure chemical compatibility and long life. Power Plant Fuel oil levels are a major applications where precise measurement is required to ensure safe operation. Endress+Hauser 5

6 Operating Principle NMS5 tank gauging system is based on the principle of gauging displacement. A small displacer is accurately positioned in a liquid medium using a servo motor. The displacer is then suspended on a measuring wire which is wound onto a finely grooved drum housing. NMS5 counts the rotation of the wire drum and calculates the traveling distance of the wire and then obtain the liquid level change. The drum is driven via coupling magnets which are completely separated by the drum housing. Outer magnets are connected to the wire drum whilst inner magnets are connected to the drive motor. As the inner magnets turn, their magnetic attraction causes the outer magnets to turn, as well, causing the entire drum assembly to turn. The weight of the displacer on the wire creates torque on the outer magnets generating change of magnetic flux. These changes generated in the drum assembly are detected by a unique electromagnetic transducer on the inner magnets. The drive motor is actuated to balance the voltage generated by variations of magnetic flux to equal the reference voltage defined by operating commands. When the displacer is lowered and touches a liquid, the weight of the displacer is reduced by liquid buoyancy force. As a result, torque in the magnetic coupling changes, which is measured by 5 sets of Hall sensors, (patented) chips which are temperature compensated. A signal, indicating the position of the displacer, is sent to the motor control circuit. As the liquid levels rise and fall, the displacer position is adjusted by the drive motor. The rotation of the wire drum is precisely evaluated to determine level value.

10 Point to Confirm Application: What will be the primary measurement function in your application? Most applications can be generalized into three classifications: level data, density data, or both. NMS5 is primarily a highly accurate level measurement gauging instrument, with the added ability to measure density. Level is derived by determining fluid surface level, interface level(s) between different liquids, as well as finding tank floor or datum plate. Density served from single-point (called spot measurements), as well as profile measurements of all liquid(s) in a tank. Surface Level: In general, larger diameter displacers have better accuracy under similar conditions. Interface Level(s): Cylindrical-shaped displacers, with rounded top and bottom, reduce resistance while moving through liquid(s). Thus, providing smoother movement and faster interface measurements, compared to flatbased displacers, particularly in density profile measurements that span the full tank height. CAUTION Note that in order for a displacer to travel down through liquid(s), displacer density (its weight divided by its volume) must be higher than liquid(s) density. Tank-bottom/Datum Plate Level: (same as for Interface Levels) Density: Since the density is the calculated result of two of more measurements, a displacer with higher volume will usually yield the most accurate density measurement. In most cases we recommend our 50mm diameter displacer for density measurement. Level and Density: When an application calls for equal importance placed on measuring both level and density, the 50mm diameter, cylindrical displacer will give the best all-around performance. Custody Transfer Material Compatibility What is the requirement for Custody Transfer approval? The 70mm, conical, 316 displacer is the choice for requirements per NMi The 110mm, conical 316 displacer is the choice for requirements per PTB What are the liquid(s) characteristics of your application? Displacers are available in three different standard materials. Material compatibility should be confirmed to ensure safe operation and optimal NMS5 performance. 316: Stainless steel is a highly versatile industrial material and provides good compatibility with a wide range of chemicals, including most white and black oils. Alloy C: This high-performance material is harder than 316, and provides excellent resistance to many of harshest corrosive chemical applications. PTFE: One of the most well-known and versatile polymer materials, this high-performance material has one of the lowest friction coefficients. It provides excellent performance in viscous/sticky liquids, and also has excellent chemical resistance to a wide range of corrosives Process Connection Size The process connection defines the tank process entry, and may affect displacer size. The standard NMS5 process connections start at 3 /DN80 and fit most tank gauging applications. Accordingly, most applications can be covered with one of the 50mm or 70mm displacer options. Smaller diameter displacers are available when the process connection is smaller. CAUTION Note that, when the 110mm diameter custody transfer approval (PTB) displacer is selected, a separate calibration and maintenance chamber is recommended between the NMS5 and tank process connection. 10 Endress+Hauser

27 Human Interface Operating Concept NMS5 is furnished with a four line illuminated liquid crystal display. With the E+H matrix driven operation, configuration is simple. Using only three keys, all parameters can be selected and modified. For example: Operation - level; interface; spot & profile density, water dip, & tank bottom Current output Relay output Maintenance prediction Calibration, etc. The display can be configured to be displayed in English, Japanese or Chinese. Measurement unit & decimal point can be also configured within NMS matrix. Operational Security The programming information can be protected by software access codes that disable all programmable parameters or by a hardware switch to prevent changes from remote transmission or the touch control keypad. A self-diagnosis function checks for any operational failures. Display (LCD) IIluminated LCD Infrared Transmitting Diaode Infrared Receiving Diaode 3 Optical Operating Elements " Touch Control" Figure 13: Display (LCD) Four line 16-digit illuminated display English, Japanese, Chinese selectable Programming Memo Function Three optical keys (touch control) for selection of matrix functions. Memo of maintenance information. Endress+Hauser 27

28 Advanced Maintenance Maintenance Prediction Maintenance Proactive Safety NMS 5 will provide advance warning of required maintenance such as replacement of worn wire etc. The operating life-span of electrical and mechanical parts of the NMS 5 are factory set within the instruments memory. This information is checked involving with the built-in clock and compared and registered in the instrument. The maintenance record can be accessed via the matrix and will provide information of alarm data (e.g. date, time, alarm type). A memo function allows the user or an E+H Service Engineer to enter maintenance data manually. Proactive safety diagnostic function warns of mechanical failure, and outputs maximum level value, e.g to local display and Fieldbus. 28 Endress+Hauser
